Statistical shape modeling of the human inner ear through micro‐computed tomography imaging
In this study, 54 cadaveric temporal bone specimens underwent high‐resolution micro‐CT imaging. Images were semi‐automatically segmented and converted to 3D surface mesh models for morphological measurement and analysis. Statistical shape models were created for the inner ear, cochlea, and vestibular system, as well as for sex‐ and side‐based subgroups.

Inner ear barotrauma was observed by compressing or decompressing guinea pigs. The barotrauma in compression was greatly influenced by auditory tube function, and, in the animals deprived of this function, we could observe far more severe damage of inner ear hair cells and far more frequent round window rupture than in animals not thus deprived ...

Ontogeny of murine bony semicircular canal form
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus
The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.

Abstract Despite documented ecomorphological shifts toward an herbivorous diet in several coelurosaurian lineages, the evolutionary tempo and mode of these changes remain poorly understood, hampered by sparse cranial materials for early representatives of major clades. This is particularly true for Therizinosauria, with representative crania best known

Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Adenovirus Vectors Target Several Cell Subtypes of Mammalian Inner Ear In Vivo
Mammalian inner ear harbors diverse cell types that are essential for hearing and balance. Adenovirus is one of the major vectors to deliver genes into the inner ear for functional studies and hair cell regeneration.

The petrotympanic canal (Huguier canal): Evolutionary, anatomical, and medical perspectives
Abstract The petrotympanic canal, traditionally referred to as Civinini's or Huguier's canal, represents an anatomical passage connecting the middle ear and temporomandibular joint (TMJ). Despite its early description, its structural complexity and functional significance have often been underestimated. In this study, we combined historical, anatomical,
